L.U.C Lunar One

In 2005, by introducing a complication for the first time in an evolution of its founding L.U.C Calibre 96.01-L, Chopard Manufacture presented one of its milestones: a large-date perpetual calendar with a degree of astronomical precision to which only a handful of Manufactures can lay claim. The L.U.C Lunar One timepiece equipped with the L.U.C 96.13.L chronometer-certified movement illustrates the trajectory of the moon with remarkable accuracy. Its perpetual calendar with orbital moon phases clearly indicates the date, day, month and leap years. It also features an additional 24-hour scale. The night star rotates around the small seconds axis, hence the term ‘orbital’. The movement represents the sky as seen from the Northern Hemisphere with the Big Dipper; as well as from the Southern Hemisphere with the Southern Cross. Calibrated by Chopard's finest watchmaking Artisans, this display boasts astronomical precision: with a time difference of just 57.2 seconds between two moons, it will take 122 years for it to show a one-day discrepancy with the real moon. Only then will it need to be adjusted. Reflecting Chopard Manufacture's perpetual quest for slenderness, the L.U.C Lunar One timepiece is also one of the very few self-winding perpetual calendars to feature a micro-rotor. The latter is made of solid gold and integrated into the movement thickness, thereby slimming it down and enabling it to be admired through the sapphire crystal pane fitted on the case-back. Engraved with the L.U.C logo and finely guilloché, this micro-rotor heralds the extreme degree of finishing lavished on L.U.C Calibre 96.13-L – of which all 355 components are produced, hand-decorated and assembled in the Manufacture's workshops. Thanks to the two stacked barrels of Chopard Twin technology, the L.U.C Lunar One model is also endowed with a 65-hour power reserve.
